Two years ago, we observed prices beyond EUR 100/kWp for build-ready, utility-scale PV project rights in Germany. In the market, we currently see low prices down to EUR 20/kWp.
Cannibalization: Victim of Its Own Success
The reason is clear: through cannibalization, PV systems are victims of their own success. When all PV systems feed in simultaneously at midday, it pushes down their own market value. In April, it stood at around 1.3 ct/kWh. The Federal Network Agency counted 573 hours of negative power prices in 2025; 600 to 900 are forecast for 2026. Pure ground-mounted PV projects are therefore increasingly difficult to make economically viable.
With a Green-Power Storage System, the Math Changes
With a green-power storage system, the calculation already looks different. Negative hours become a charging window; higher volatility from geopolitical tensions becomes arbitrage revenue. As grid connection capacity becomes increasingly scarce in many regions, the legislator is also promoting grid overbuild and the co-location of battery storage and renewables.
In concrete numbers: the BET BESS co-location index shows an average PV revenue of around EUR 50/MWh over the past twelve months. With a green-power storage system in front of it, the value rises to around EUR 90/MWh – nearly a doubling, with additional upside from switching to mixed operation with grey-power offtake once the grid is expanded later.
Entering at the Lowest Sentiment?
On the stock exchange, you buy when sentiment is at its lowest. Could that be exactly the moment for PV project rights right now?
